Synthesis, Electrochemical Characterization and Photocatalytic Application of Ceion Doped ZnO nanoparticles using Leaf Extract of SesbaniaGrandiflora by Green Method

Nanosized ZnO particles of specific morphology were synthesized using the plant leaf extracts of Sesbania grandiflora (Agathi keerai). The structures and morphology of these fabricated ZnO naoparticles and Ce ion doped ZnO nanoparticles were characterized by FTIR, SEM-EDAX, AFM and PL. Photodegradation and electrochemical behaviour of the nanoparticles were studied. The aqueous Sesbania Grandiflora leaf extract acts as a solvent with multiple roles as promoter and capping agent for the synthesis of ZnO and Ce ion doped ZnO nanoparticles. Photocatalytic degradation was also investigated with Bismarck brown dye under UV-irradiation source. The ZnO and Ce ion doped ZnO nanoparticles exhibited potential photocatalytic activity towards the degradation of Bismarck brown dye. Green synthesis using Sesbania Grandiflora is found to be the best capping agent for synthesizing nanoparticles.
